|Gentoo Linux Security Advisory
Title: libxml2: Denial of Service (GLSA 201203-04)
Date: March 06, 2012
A hash collision vulnerability in libxml2 allows remote attackers
to cause a Denial of Service condition.
libxml2 is the XML C parser and toolkit developed for the Gnome project.
Vulnerable: < 2.7.8-r5
Unaffected: >= 2.7.8-r5
Architectures: All supported architectures
libxml2 does not properly randomize hash functions to protect against
hash collision attacks.
A remote attacker could entice a user or automated system to open a
specially crafted XML document with an application using libxml2
resulting in a Denial of Service condition.
There is no known workaround at this time.
All libxml2 users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/libxml2-2.7.8-r5"
